One of our favorite things about Determinate Secure Packages is that adoption doesn't involve refactoring or building out an integration. You swap out a flake reference to get started and `nix flake update` to pull security fixes. That's really it 📦 🔐 ❄️ 🚀 determinate.systems/secure-packa...

Nobody goes to work saying "I can't wait to achieve compliance today." But like it or not, cryptography standards like FIPS are non-negotiable if you want to work with many US federal agencies, so better to make it all as painless as possible. 🧵 👇

The supply chain story has been pretty rough lately, eh? Wily vulnerabilities, sophisticated exploits, vast attack surfaces, and woefully uneven remediation (if any!) have put us all on edge. We at DetSys are hard at work on this problem and this week we're going to tell you a whole lot about it 🧵👇

Nix adoption often starts with one dev solving problems for themselves. At work, the question becomes: how can it be made reliable and secure for teams? DetSys co-founder @grahamc.com recently joined Open Source Ready to talk about this jump. Take a listen 🎤 ❄️ 🚀 www.heavybit.com/library/podc...
